Tanzanite is found in only one location in the world, a small, protected mining area in Tanzania at the foothills of Mount Kilimanjaro. This singular origin makes Tanzanite one of the most geographically exclusive gemstones on Earth.

Unlike diamonds or sapphires, Tanzanite exists in a finite supply. With no alternative sources worldwide, its rarity is defined not by demand, but by nature itself.

High-quality Tanzanite has become increasingly sought-after due to its limited supply and growing global appreciation. Its rarity and provenance make it appealing to collectors who value exclusivity.

Yes at Tanzanite International we specialise in loose Tanzanite.

Due to the fact that tanzanite is only found in one place in the world and is formed as the result of a rare geological phenomenon, most estimates are that there is enough tanzanite in the ground to last for another 10-12 years.

Tanzanite is softer than a diamond and has a similar hardness to that of an Emerald, but is less brittle. Tanzanite measured 6.5 to 7 on the Mohs Scale of Hardness. Simple precautions should be taken to preserve its beauty. Tanzanite is ideally suited for wear in dress rings, earrings and necklaces, rather than everyday wear.  As such, we do not recommend Tanzanite in engagement rings that are worn every day.
